Clarence Ratzke, 74, of Round Lake, was arrested and charged with predatory criminal sexual assault of a child, said Round Lake Beach Deputy Police Chief Rich Chiarello. Ratzke was in Lake County Jail on Tuesday in lieu of $250,000.

Authorities said additional charges may be filed after review by the Lake County State's Attorney's Office.

Ratzke was arrested Oct. 10 after authorities were contacted by the Illinois Department of Children and Family Services to investigate into an incident involving the man and a child under 13 in 2006.
